IPC: F24F7/08
Filed: 2002-02-25
Abstract: <P>PROBLEM TO BE SOLVED: To provide a system which recovers heat of air conditioning efficiently during ventilation and is used for private houses.  <P>SOLUTION: A centralized ventilating fan 110 is connected to a heat exchanger 120 through an intake and exhaust pipe. Heated exhaust air from each room comes through the fan 110. Heat of the exhaust air is recovered by the heat exchanger 120 and the air is discharged out of the system. The heat exchanger 120 is connected to a tank 130 through water feed and drainage pipes. Water is pumped up from the tank 130 by a pump 140, heated in the heat exchanger 120, and brought back to the tank 130. Using Peltier elements, the heat exchanger 120 cools the exhaust coming from the centralized ventilating fan 110 as well as heats the water from the tank 130. On the whole, the heat of the air from each room is efficiently transferred to the water. Because the heat is transferred efficiently through the Peltier elements, the temperature of the water from the heat exchanger is made higher than that of the exhaust air.  <P>COPYRIGHT: (C)2003,JPO
